Overview
The TOA PM-660D is a durable desktop paging microphone designed for public‑address and commercial PA systems. It features a moving‑coil (dynamic) element with a unidirectional (cardioid) polar pattern, anti‑vibration construction and a large push‑to‑talk switch with locking lever for continuous announcements. A talk‑switch contact is provided for remote control of external equipment.

• Dynamic moving‑coil element with cardioid/unidirectional pickup for clear speech.
• Large push‑to‑talk switch with locking lever and extra contact for remote control (e.g., amplifier or chime).
• Balanced 600 Ω output via 2.5 m cable terminated with a 5‑pin DIN plug (PM‑660D variant).
• Anti‑vibration design reduces handling noise during use.
• Robust construction: zinc‑plated steel head and ABS resin body.

Use cases
Ideal for reception desks, retail and commercial paging, classrooms, small auditoriums and other PA applications where reliable desk‑mounted paging and remote switching are required.

Installation & safety
Check amplifier input compatibility and wiring for the 5‑pin DIN connector. The talk‑switch remote contact is rated for up to 30 V DC and ≤500 mA — ensure connected equipment does not exceed these ratings. Refer to the official datasheet for wiring diagrams and full installation guidance.

Compliance & documentation
Please consult the provided datasheet and local regulations for any applicable conformity marks (e.g., CE / UKCA). The official product page and datasheet contain full technical and dimensional details.
